Step-by-step explanation:
(a) Add the parts of the ratio, 1 + 3 = 4 parts
Divide 260 by 4 to find the value of one part of the ratio.
260 ÷ 4 = 65 ← value of 1 part of the ratio, thus
3 parts = 3 × 65 = 195
260 in the ratio 1 : 3 = 65 : 195
(b)
Given
3 : 5 ← divide both parts of the ratio by 3
:
= 1 :
→ A

<h3>Answer: Parallelogram</h3>
You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).
An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram
Side note: The other diagonal is either u-v or v-u depending on your reference point.
